Class ImageBinarizationMethod

java.lang.Object
    extended by com.aspose.words.ImageBinarizationMethod

public class ImageBinarizationMethod 
extends java.lang.Object

Utility class containing constants. Specifies the method used to binarize image.

Example:

Shows how to set the TIFF binarization error threshold when using the Floyd-Steinberg method to render a TIFF image.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.getParagraphFormat().setStyle(doc.getStyles().get("Heading 1"));
builder.writeln("Hello world!");
builder.insertImage(getImageDir() + "Logo.jpg");

// When we save the document as a TIFF, we can pass a SaveOptions object to
// adjust the dithering that Aspose.Words will apply when rendering this image.
// The default value of the "ThresholdForFloydSteinbergDithering" property is 128.
// Higher values tend to produce darker images.
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.TIFF);
options.setTiffCompression(TiffCompression.CCITT_3);
options.setImageColorMode(ImageColorMode.GRAYSCALE);
options.setTiffBinarizationMethod(ImageBinarizationMethod.FLOYD_STEINBERG_DITHERING);
// The default value of this property is 128. The higher value, the darker image
options.setThresholdForFloydSteinbergDithering((byte) 254);

doc.save(getArtifactsDir() + "ImageSaveOptions.FloydSteinbergDithering.tiff", options);
